title: Fertility after colorectal resection for endometriosis: results of a prospective study comparing laparoscopy with open surgery.
abstract: OBJECTIVE
  To determine whether the surgical route of colorectal resection for endometriosis is a determinant factor for fertility.
  
  
  METHODS
  Prospective study.
  
  
  METHODS
  Tertiary-care university hospital.
  
  
  METHODS
  Fifty-two patients with endometriosis were randomly assigned to laparoscopic or open surgery.
  
  
  METHODS
  Laparoscopically assisted vs. open colorectal resection.
  
  
  METHODS
  Evaluation of fertility outcomes spontaneously and after assisted reproductive therapy.
  
  
  RESULTS
  The mean follow-up was 29 months. Among the 28 patients wishing to conceive, 11 (39.3%) became pregnant. Overall cumulative pregnancy rate at 52 months for these patients was 45.1%. For patients with or without infertility, the cumulative pregnancy rate was 37.6% and 55.6%, respectively, and the cumulative spontaneous pregnancy rate 13.3% and 36.5%, respectively. All the spontaneous pregnancies were observed in the laparoscopy group.
  
  
  CONCLUSIONS
  This study demonstrates that spontaneous pregnancy is more frequent after laparoscopy compared with open surgery for colorectal endometriosis.
